Currently the librem5-r4-u-boot.dtsi ( text below ) includes 
imx8mq-u-boot.dtsi and I tried deleting the signed-hdmi and including a 
signed-dp in it's place. Now instead of an error about a missing 
"signed_hdmi_imx8m.bin" I get an error about a missing 
"signed_dp_imx8m.bin" so I know I'm having an effect but not enough of 
one.

&pinctrl_uart1 {
         u-boot,dm-spl;
};

&uart1 { /* console */
         u-boot,dm-spl;
};

&binman {
         /delete-node/ signed-hdmi;

         signed-dp {
                 filename = "signed_dp_imx8m.bin";

                 signed-dp-imx8m {
                         filename = "signed_dp_imx8m.bin";
                         type = "blob-ext";
                 };
         };
};
